Trusted Time Stamp
The standardisation of the trusted time stamp can be seen as the electronic replacement of the
present postmark on regular mail. As such, the service requires electronic security features to
reproduce some characteristics of the traditional postmark such as a time and date stamp given by
a postal operator acting as a trusted third party in a communication.
The service is a first example of a Global Postal Trust Service (GPTS) allowing Postal operators to
bring e-mail up to the same level of acceptance that hard-copy mail currently enjoys. Via the trusted
time stamp service, e-mail messages will be given, by the Postal operators acting as a trusted third
party, a tamper-detection feature with a secure time and date stamp (i.e. the trusted time stamp).
Secure electronic postal services (SEPS) interface specification
Part A: Concepts, schemas and operations
This document specifies a standard XML interface that will enable software applications to call a
secured electronic postal service (SePS), provided by a postal operator. It also describes the
functionality and edit rules of the actual technical specification artifacts, which are represented by
an XML Schema (XSD) and an associated Web Services Definition Language (WSDL)
specification.
Part B: EPCM Service
This document specifies a secured electronic postal service, referred to as the Electronic Postal
Certification Mark (EPCM) service, which provides a chain of evidence, stored by an operator as a
trusted third party, to prove the existence of an electronic event, for a certain content, at a certain
date and time, and involving one or more identified parties.
Functional specification for postal registered electronic mail
This standard defines the functional specification of a secure electronic postal service, referred to
as the postal registered electronic mail or PReM service. PReM provides a trusted and certified
electronic mail exchange between mailer, designated operators and addressee/mailee. In addition,
evidence of corresponding events and operations within the scope of PReM will be generated and
archived for future attestation.
Exchange of name and address data
This standard facilitates the electronic communication of international name and address data sets
from mailer to postal operator; from postal operator to postal operator; from postal operator to
mailer and between mailers. It supports such communication both in the form of S42 data elements
and in the form used in printed postal addresses. The standard is based on two W3C XML
Schemas and relies on S42 for definitions of elements, element sub-types and country based
templates.
Statement of mailing submission
This standard specifies a methodology that allows postal operators to define statements of mailing
submission customised according to their environment and applications. It defines information that
could be collected within the mailer’s domain and transmitted to the postal domain to support
processing applications related to major postal functions, namely operations, finance and
marketing. It also defines the organisation of data originating in the mailer’s domain into messages
by describing data content, format and communication protocols and provides a detailed analysis
and recommendations for implementing countermeasures against application level security threats,
particularly those relating to postal revenue protection in controlled mail entry settings.
